COMBINED IRON AND STEEL BAR.

SFECIFICATION forming part of Letters Patent No. 328.652. dated October 20, 1885.

(No model.)

To all whom it may concern:

Be it known that I, LoUIs G. CLAUDE, a citizen of the United States, residing in the city, county, and State of New York, have invented certain new and useful Improvements in Bars of Combined Iron and Steel, of which the following is a specification.

This invention relates to bars of combined iron and steel designed, primarily, for use in IO the manufacture of horseshoes by machinery,

but also applicable to other industrial uses.

Figure 1 of the accompanying drawings is a cross-section of the pile or ingot from which my improved bar is to be rolled. Fig. 2 is a cross-section of the plain bar rolled therefrom. Fig. 3 is a plan of this bar, the white portions indicating steel and the portions shaded by a tint of parallel lines denoting wrought-iron. Fig. 4 is a plan, on a smaller scale, of the fluished bar embodying my entire invention.

Fig. 5 is an edge View thereof partly in longitudinal section. Fig. 6 is a transverse section thereof out in the plane of the line 6 6 in Figs. 4 and 5, and Fig. 7 is a transverse section cut in the plane of the line 7 7 in these figures. Figs. 6 and 7 are on the same scale as Fig. 2. Fig. 8 is a fragmentary front eleration of the rolls for reducing the plain bar shown in Fig. 3 to the ribbed bar shown in Fig. 4, being partly in vertical section; and Fig. 9 is a fragmentary transverse section of these rolls. The remaining figures illustrate modifications. Figs. 10 and 11 show modified piles. Fig. 12 is a plan of a modified ribbed bar; Fig. 13 is an edge view of another modification of the ribbed bar,and Fig. 14 is aplan thereof.

' I will first describe the preferred mode of manufaoturin g my improved bar, referring for 40 that purpose to Figs. 1 to 9. The pile shown in Fig. 1 is first built up, using two bars, A A,of soft steel, two angle-bars, B B,of wroughtiron, and an eye-bar, B,also of wrought-iron. The bars B B B are or may be muck-bars or puddle-bars, or other suitable form of crude wrought iron. The several bars are combined together, as shown, the steel bars or cores being separated from each other and enveloped by the iron. This pile is heated and rolled in the usual manner until a bar, 0, of combined iron and steel is produced having the cross-section shown in Fig. 2. This bar C consists of two cores of steel, a a, an intervening portion of iron, 0, and two iron flanks, b b. The steel cores constitute the greater portion of the bar,and come nearly or quite to the surface on the upper and lower sides.

In the operations of heating and rolling the iron on the upper and lowersurfaces is greatly reduced in thickness, being partly burned away, partly sealed off in rolling, and partly rolled into and incorporated with the steel. It is immaterial whether any iron remains upon these surfaces of the bar or not. The steel cores A A in the pile might be devoid of any covering ot'iron in the upper and lower sides except that the exposed surfaces of the steel would in that case be blistered and injured. In Fig. 3 the rolled bar is shown in plan, it being assumed that the steel cores are denuded of iron 'on the flat sides of the bar and exposed to view. The plain bar C thus made embodies a portion of my present invention, and is adapted to several industrial uscssucl1 as for the tires of wagonwhcels, the frames of iron structuies, as blanks for the manufacture of certain kinds of tools, such as claw-bars for drawing railwayspikes, for instance, and for the manufacture of horseshoes. For the latter purpose the bar should be rolled somewhat thinner to form a plate, and it may then be worked up according to the method disclosed in my application for patent executed this day on improvements in the manufacture ofhorseshoes of combined iron and steel, application No. 150,779, filed December 19, 1884.

The next operation,which completes the bar according to my present invention, consists in passing the plain bar (shown in Figs. 2 and 3) through the rolls, (shown in Figs. 8 and 9,) whereby it is transformed into the bar shown in Figs. 4 and 5. This bar is distinguished by having transverse ribs or projections D D formed upon one side, the other side being, preferably, plane. The bar thus made is designed to be used in the manufacture of horseshoes with solid calks. The ribs D D are spaced the same distance apart as the toe-call; is from the heel-calks on the horseshoewhich is to be made from it. The ribs in the preferred construction do not extend entirely across the bar, nor are they'continuous. Each rib consists of three projections, a long middle projection, D, and two short projections DD, at the sides. The projections D are destined to form the toe-calks of the finished shoes, and the projections D D" to fOlDl the heel-calks thereof. The middle stripe, c, of iron passes through the middles of the several projections D, and the iron flanks b I) pass through the outer sides of the projections D D This, however, is not essential, as the latter projections may be located inside of the iron portions, being thereby wholly of steel. The projections D are formed with steel ends and iron middle. This bar is admirably suited for the manufacture of horseshoes with solid steel calks, it being only necessary to punch out the shoes of curved or U-shaped form with the toes, including the projections D, and the heels, including the projections D D The method of manufacturing such shoes is fully set forth in my application executed this day for patent on improvements in the manufacture of horseshoes with solid calks application No. 150,889, filed December 20, 1884. The rolls for fOIDling this bar consist of a plane roll, E, and a grooved roll, F, the latter being formed with grooves f f, corresponding to the projections on the bar. The bar 0 is passed through these rolls only once, being thus reduced to the thickness desired between the projections, and the portions forming the projections entering the grooves f f, being thus left standing the thickness of the original plate 0. This method of rolling has before been employed for rolling iron, and forms of itself no novel portion of my invention.

The improved compound bar made according to my invention has the advantage for the manufacture of horseshocs, that it admits of the ready-bent shoes being punched out of it at asingle operation, eachshoe being strengthened by the steel stripes a at extending through its legs or sides and having iron flanks, b b, which facilitate the subsequent operations of forming the creases for the nail-heads, and punching the nail-holes, and also having an iron center, 0, from which the toe-clip may be readily struck up. Furthermore, when the ribbed bar is employed the shoes thus struck out are ready formed with the toe and heel calks, which are principally of steel, and hence well adapted to resist wear. For any other purpose requiring similar conditions the improved bar will have similar advan tages. For example, a wagon-tire made from this bar will wear hollow in its iron middle,

leaving the steel portions standing to give greater adhesion and prevent side slip, instead of wearing convex, as do the tires now in use. And for a claw-bar or similar tools,

I will now proceed to describe the modification illustrated in the drawings. Instead of the pile shown in Fig. 1 any other suitable pile may be employed, andv the shape of the steel cores may be varied to better adapt the bar to the special use for which it may be designed. Fig. 10 shows a simple form of pile wherein the steel bars AA are separated by .an iron plate, B, and inclosed by four plates, B B. Fig. 11 shows a pile especially designed for producing wagon-tires, the steel cores A A being of approximately triangular form with rounded edges, and inclosed between two grooved bars, B B, of wroughtiron. The bar rolled from this pile will have steel cores projecting into its corners, there to take the Wear and prevent the tire wearing into rounded form. The ribs D D on the bar may be continuous instead of being interrupted or divided into three projections. Fig. 12 shows a bar wherein the ribs are thus continuous. They do not extend quite to the edge of the bar, a marginal space being left on a plane with the general surface of the bar to facilitate the separating of the bar from the roll F.

Figs. 13 and 14 show a modified form of the transverse ribs. These are made with one beveled or inclined side and one abrupt side, as shown. This bar is designed for the manufacture of a shoe with very low beveled calks.

What I claim, and desire to secure by Letters Patent, is
